To determine the nature of the solution set of a quadratic equation, it is necessary to first express it in standard form 

This can be done by simply switching the first and second terms:

The key to determining the nature of the solution set is to examine the discriminant  . Setting , the value of the discriminant is 

The discriminant has a negative value. It follows that the solution set comprises two imaginary values.

To determine the nature of the solution set of a quadratic equation, it is necessary to first express it in standard form 

This can be done by adding 17 to both sides:

The key to determining the nature of the solution set is to examine the discriminant 

. Setting , the value of the discriminant is 

This value is negative. Consequently, the solution set comprises two imaginary numbers.

To determine the nature of the solution set of a quadratic equation, it is necessary to first express it in standard form 

To accomplish this, first, multiply the binomials on the left using the FOIL technique:

Collect like terms:

Now, subtract 18 from both sides:

The key to determining the nature of the solution set is to examine the discriminant . Setting , the value of the discriminant is 

The discriminant is a positive number, so there are two real solutions. Since 73 is not a perfect square, the solutions are irrational.

Now, add 18 to both sides:

The key to determining the nature of the solution set is to examine the discriminant . Setting , the value of the discriminant is 

This discriminant is negative. Consequently, the solution set comprises two imaginary numbers.

To determine the nature of the solution set of a quadratic equation, it is necessary to first express it in standard form 

This can be done by switching the first and third terms on the left:

The key to determining the nature of the solution set is to examine the discriminant 

. Setting , the value of the discriminant is

.

The discriminant is a positive number but not a perfect square. Therefore, there are two irrational solutions.

The first step to solving an equation where  is in a radical is to isolate the radical. To do this, we need to subtract the 5 from both sides.

Now that the radical is isolated, clear the radical by raising both sides to the power of 3. Note:

Now we want to isolate the  term. First, subtract the 5 from both sides.

Finally, divide both sides by  to solve for .
